A blog about the things boat builders do that cost you money, and other eclectic newsy musings of interest to boaters. FOR FIVE ALTERNATIVE WAYS TO READ THE MARINE INSTALLERS RANT FOLLOW THE LINK BELOW. Its exactly what it looks like, a field. A neutral place generally free of magnetic sources. I say this because there is no place on earth free of magnetic fields. We all live on a giant roundish rotating magnet. But in this empty field there isnt much. On our planet ambient background magnetic fields typically vary around 25 to 65 microTeslas. The extra microTeslas on you see on the meter are largely coming from power lines and other things around me. On the whole this isnt much and the local field is reading zero. However, a large green field isnt boat by any measure, and this is where we start. Can boat batteries shock you? The answer is yes and I can in an empirical way say this is the truth. The way you can test this is on a stinking hot humid day in Florida whilst in the bowels of the boat sweating like a pig have your wet arm come in contact with the positive and negative battery terminals. Will this kill you? No! Will  the shock hurt you? Not really. But in a cramped and confined hot space can it startle you causing your head to jerk up smacking the underside of the deck and let the wrench in your hand at the same time bridge the terminals causing notable arcy sparky stuff to briefly happen? Yep I know from personal experience this is very possible, and if there was hydrogen sulfide gas leaking from the batteries at the same time there might be a kaboom. BTW the legal department on the fourth floor reminds me to tell everyone to not try to invent or test ways to have large batteries shock you. If youre going to try this anyway at least make sure you video it and use the revenue to help pay the medical bills. Although the voltage is low the amount of  the stored energy is large and the law of unintended circu*stances can raise its ugly head.
